The branch stable/14 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=8c4eaac1534e0486bd0fc6816ccb59fc348a5707 commit 8c4eaac1534e0486bd0fc6816ccb59fc348a5707 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2023-10-09 10:30:22 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2023-10-12 04:08:20 +0000 buf: Add sysctl flag CTLFLAG_TUN to loader tunable The sysctl variable 'vfs.unmapped_buf_allowed' is actually a loader tunable. Add sysctl flag CTLFLAG_TUN to it so that `sysctl -T` will report it correctly. No functional change intended.
